FreeIPA installation on the NFS node

IPA services are used to provide account management and centralized authentication.

To customize your installation of FreeIPA, enter the following parameters in input/security_config.yml.

To set up IPA services for the NFS node in the target cluster, run the following command from the utils/cluster folder on the control plane:

cd utils/cluster
ansible-playbook install_ipa_client.yml -i inventory -e kerberos_admin_password="" -e ipa_server_hostname="" -e domain_name="" -e ipa_server_ipadress=""
Hostname requirements

  • The hostname should not contain the following characters: , (comma), . (period) or _ (underscore). However, the domain name is allowed commas and periods.

  • The hostname cannot start or end with a hyphen (-).

  • No upper case characters are allowed in the hostname.

  • The hostname cannot start with a number.

  • The hostname and the domain name (that is: hostname00000x.domain.xxx) cumulatively cannot exceed 64 characters. For example, if the node_name provided in input/provision_config.yml is ‘node’, and the domain_name provided is ‘omnia.test’, Omnia will set the hostname of a target cluster node to ‘node000001.omnia.test’. Omnia appends 6 digits to the hostname to individually name each target node.

Note

Use the format specified under NFS inventory in the Sample Files for inventory.
